site to Site vpn with two client interfaces

Hi guys,

I am stuck with the configuration here...

We have many remote sites with site to site VPN, Head Office we hav asa 5540 and clients we have Cisco 2800, Some of the sites have redandunt connnections with two different ISPs.

We want to setup VPN on both interfaces, in case one interface is down the other one shud comeup..

so any body with experience of such scenarios or can help us?

Re: site to Site vpn with two client interfaces

Hi,

Having an ASA as the VPN server and 2800 as client you can configure both WAN interfaces on the routers to establish the VPN to the ASA.

By means of IP SLA (or a routing protocol), you configure the router to use the primary Internet connection to establish the tunnel to the ASA and if it fails to use the backup internet connection to establish the tunnel to the ASA.


The good thing is that when the primary connection recovers, the tunnel can be restablished through this link again.

Re: site to Site vpn with two client interfaces

the Client have only one router with two interfaces connecting to two ISPs, so how can we reset the tunnel using SLA..
